Leaflet supports Web Map Service (WMS) layers, GeoJSON layers, Vector layers and Tile layers natively. Many other types of layers are supported via plugins.. Like other web map libraries, the basic display model implemented by Leaflet is one basemap, plus zero or more translucent overlays, with zero or more vector objects displayed on top.
The 'Transport Map' layer, when sufficiently zoomed-in, shows routes and route numbers in red. Go to OpenStreetMap and zoom into the general area where the route runs. Switch to the "Transport Map" layer using the 'Layers' sidebar on the right. Now you should see all the transit routes highlighted on the map, with numbers indicating the route ...
Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between a relational database and the memory (usually the heap) of an object-oriented programming language.
GeoPDF is a line of map and imagery products created by TerraGo software applications. GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications. However, GeoPDF products conform to published specifications including both the OGC best practice for PDF ...
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
Topological maps are straight-line diagrams or schematics that display not only the routes, but also other information such as stations and travel zones (as in the case of the London Underground Tube map). The maps are not drawn to scale, and distance and direction are subject to change and variation, but the relationship between points is ...
Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [37] [52] [53] [54] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...
To overcome the CPU intensive on-the-fly rendering problem, application developers started using pre-rendered map tiles. Several open and proprietary schemes were invented to organize and address these map tiles. An earlier specification for this is the Tile Map Service (TMS). It is simpler than WMTS.
